HMT310 Humidity and Temperature Transmitter
Reliable Vaisala
HUMICAP® Technology
The HMT310 incorporates the latest
generation Vaisala HUMICAP
®
sensor. The sensor is a capacitive
thin-film polymer sensor providing
high accuracy, excellent long-term
stability and negligible hysteresis. It
is insensitive to dust, particulate dirt
and most chemicals.
Several Outputs, One
Connector
The HMT310 is powered up with
10 ... 35 VDC. It has two analog
outputs and an RS232 serial output.
The output signal and the supply
power travel in the same cable, the
only cable connected to the unit.
Chemical Purge
Chemical purge helps to maintain
measurement accuracy between
calibration intervals. It involves
heating the sensor to remove harmful
chemicals. The function can be
initiated manually or programmed
to occur at set intervals.
Optional Functions
The following optional functions
are available: several probes for
various applications, calculated
humidity quantities, variety of
mounting kits, rain shield, sensor
protection options and probe cable
lengths, warmed probe and sensor
heating for high humidity conditions
(HMT317), and chemical purge for
applications risking an interference
with chemicals in the measuring
environment.
